A lady came through my line the other day with her 5 year oldish daughter.

as i was ringing her up, her daughter started whistling. the mother fwipped around and yelled at her to stop RIGHT NOW! i had a brief thought that the daughter had been whistling all day and annoying the hell out of her mother, but mommy then said "only boys whistle!" the mother then turned back to me and looked BEYOND embarassed. she apologized to me, saying 'she has big brothers....'
